  strongly 
  pronounced 
  diagonal 
  round 
  costa 
  reaching 
  from 
  the 
  

   humeral 
  to 
  the 
  apical 
  callus 
  ; 
  the 
  pygidium 
  is 
  vertical 
  or 
  slightly 
  

   flexed 
  forwards 
  ; 
  the 
  abdominal 
  segments 
  are 
  much 
  compressed 
  

   laterally 
  ; 
  the 
  pectus 
  is 
  very 
  hairy, 
  and 
  the 
  propygidium 
  and 
  the 
  

   abdominal 
  segments 
  are 
  completely 
  or 
  partly 
  scaly 
  ; 
  inner 
  claw 
  of 
  

   the 
  anterior 
  tarsi 
  cleft 
  in 
  the 
  middle, 
  outer 
  claw 
  basal 
  and 
  quite 
  

   rudimentary, 
  claws 
  of 
  the 
  intermediate 
  and 
  posterior 
  legs 
  simple 
  

   and 
  single 
  ; 
  anterior 
  tibiae 
  strongly 
  tri-dentate, 
  the 
  teeth 
  about 
  equi- 
  

   distant 
  ; 
  posterior 
  femora 
  and 
  tibiae 
  enormously 
  developed 
  in 
  the 
  

   male, 
  and 
  with 
  the 
  inner 
  angle, 
  and 
  sometimes 
  the 
  outer 
  (crassipes) 
  

   produced 
  into 
  a 
  long, 
  acute, 
  or 
  pluri-dentate 
  process 
  ; 
  in 
  this 
  sex 
  the 
  

   joints 
  of 
  the 
  hind 
  tarsi 
  are 
  very 
  short 
  and 
  not 
  free. 
  

  

  The 
  insects 
  included 
  in 
  this 
  genus 
  are 
  far 
  from 
  common. 
  They 
  

   are, 
  I 
  believe, 
  as 
  a 
  rule, 
  crepuscular 
  or 
  nocturnal, 
  although 
  I 
  am 
  

   informed 
  that 
  H. 
  armata 
  has 
  been 
  caught 
  on 
  the 
  wing 
  in 
  the 
  

   afternoon. 
  I 
  have 
  found 
  it, 
  and 
  also 
  H. 
  crassipes, 
  on 
  a 
  sultry 
  

   morning, 
  crawling 
  on 
  the 
  ground. 
  H. 
  auriventris 
  I 
  have 
  never 
  

   caught 
  flying 
  in 
  the 
  daytime, 
  and 
  most 
  of 
  my 
  examples 
  were 
  found 
  

   by 
  me, 
  either 
  dead 
  or 
  nearly 
  so, 
  but 
  still 
  limp, 
  and 
  in 
  the 
  act 
  of 
  

   being 
  dragged 
  by 
  ants 
  to 
  their 
  nests. 
  

  

  The 
  genus 
  is 
  strictly 
  South 
  African, 
  and 
  seems 
  to 
  be 
  restricted 
  to 
  

   the 
  Cape 
  Colony 
  ; 
  it 
  includes 
  eight 
  species.
